Describe a seasonal weather pattern from a table
Read an illustrative monthly temperature table, describe its pattern and limits, and connect the activity with Maryland Grade 3 science references.
The Maryland science directory (archived state copy) links the Next Generation Science Standards publisher. The state standards catalog identifies the 2013 NGSS framework. The Publisher’s September 2017 DCI arrangement of the 2013 Next Generation Science Standards supplies the selected expectation and its practices, core ideas, crosscutting concepts, clarifications, and boundaries. Its September 2017 arrangement date is not a new Maryland adoption. The live MSDE site displayed a maintenance notice during review and linked an archived backup; working archived state references are labeled here. Check the school’s course plan and MSDE updates for later changes. This activity selects a Grade 3 expectation. It is one part of a science course, not a complete curriculum.
What does this spring record actually show?
A fictional school’s class receives three monthly mean temperatures: March 7°C, April 12°C, and May 17°C. These invented values are for reading practice, not Maryland climate normals or a real station record. Students should arrange the months in time order, make a labeled bar graph, and describe the pattern in this supplied spring record. Ask whether the table guarantees that every day in May was warmer than every day in March.
Explain the evidence or model
The recorded monthly means increase from 7°C to 12°C to 17°C. Each step is an increase of 5°C. A graph should label the months and use one consistent temperature scale so the bars can be compared fairly. The supported statement is that the monthly means rose across these three months in the illustrative record. A monthly mean summarizes many daily observations. It does not describe every day, so a cooler May day could still occur. Nor can one short record establish what usually happens every spring. Describing a usual seasonal pattern requires suitable observations across seasons and years.
| Month | Mean temperature |
|---|---|
| March | 7°C |
| April | 12°C |
| May | 17°C |
What to check in the explanation
Look for a title, units, and an even numerical scale on the graph. If the child draws equally tall bars because each value occupies one table row, return to the quantities. Separate observation from prediction: May’s recorded mean is 17°C, while next May’s temperature is unknown from these data. The selected expectation concerns representing weather observations to describe seasonal patterns. Its assessment boundary excludes climate change. This task therefore does not ask students to attribute a trend to climate change or to treat invented values as evidence about Maryland’s actual climate.
Plan the next activity
- Put the months in chronological order and label the units.
- Draw bars using a consistent scale and compare their heights.
- Write one supported pattern and one conclusion the record cannot support.
Replace the invented record with a teacher-selected local weather dataset that includes multiple seasons and years. Identify the station, dates, units, and whether the entries are daily observations, monthly summaries, or long-term averages. Use tables and bar graphs or pictographs to describe the seasonal pattern in that source. Maryland’s science directory also highlights environmental literacy and the Chesapeake Bay watershed; local weather can give a classroom question a place-based context without inventing a regional result. Keep the source and the child’s representation together. Follow the school’s sequence for wider weather and climate instruction.

How does Grade 3 connect to Maryland’s science assessment?
Grade 3 is not a Maryland Integrated Science Assessment (MISA) grade. The archived state guidance identifies MISA in Grades 5 and 8 and a high-school Life Science end-of-course assessment. Grade 5 draws on Grades 3–5 expectations; Grade 8 draws on Grades 6–8. Check current MSDE and school directions for later changes. Follow the school’s assigned assessment pathway and current directions. Instruction continues in other grades. The independently published practice here uses its own question counts, timers, and scoring; it is not an official state assessment or a prediction of a state score. Read the official guidance.
Can a monthly mean tell us that every day in that month was warmer?
No. A mean summarizes observations and can hide day-to-day variation. Compare like summaries, and use daily records for claims about individual days.
Where should I check the complete science requirements?
Start with the Maryland science standards directory and its linked publisher NGSS document. Read the Grade 3 expectations and their supporting information alongside the school’s curriculum plan. The selected investigation and resources here do not certify complete course coverage. Read the official guidance.
